    Solve for x

    I wonder if anyone can help me. I would like solve the following equation for x.

    y= (4.211)*(x to the power of 0.7635)

    I know you can use log functions to reduce the exponent, I just don't know how to get rid of the log function of x as the last step. So, in the end I get as far s this

    ((y/4.211))/0.7635 = Log (x)

    Thank you so much!

    From there you can raise 10 to the value of the left hand side to get x but you don't need to use logs to solve it. After all you wouldn't use logs to solve x^2 = 4 would you

    Divide by 4.211 as you did and raise both sides of the equation to the \frac{1}{0.7635}. This will give an exponent on the x of x^{{0.7635} \times \frac{1}{0.7635}} = x^1 = x

    4.211 x^.7635 = y

    x = (y / 4.211)^(1 / .7635)
